Definitions
- the present application relates to the induced remineralization of human enamel, and more particularly to the construction of apatite on dental material.
- the application also relates to the induced remineralization of human dentin, and more particularly to the formation of dentin on dental material.
- Teeth are compounds of apatite and proteins. They are very hard biomaterials based on calcium and phosphate.
- the enamel, the outer layer of the tooth crown is the hardest part of the tooth and contains no living cells.
- Enamel consists of inorganic crystals which have typical highly oriented arrangements. Enamel is a tissue that, once formed, remains virtually unchanged throughout life as the cells involved in building the teeth die off once tooth formation is complete.
- a finished enamel consists of about 95% by weight of apatite, about 3% by weight of proteins and lipids, and about 2% by weight of water.
- Dentin is the name given to a bone-related hard substance that forms the core of the tooth in mammals and humans. Dentin is about 30% of a cell-free organic matrix, in particular glycoproteins, are embedded in the collagen fibers. The inorganic constituents are mainly hydroxylapatite, fluorapatite and small amounts of carbonates, magnesium and trace elements.
- WO 03/099234 A1 describes a method for growing apatite
- Tooth material comprising the steps:
- an alkaline solution in particular an aqueous alkaline solution, or an alkaline gel is preferably used as the alkaline medium.
- the alkaline medium preferably has a pH of 7.1 to 14, in particular of at least 7.3, more preferably of at least 7.5 and most preferably of at least 8 and preferably up to 10, more preferably up to 9. It is particularly advantageous to use as the alkaline medium a composition that is tolerated in the oral cavity of humans, for example a 0.05 to 1 N NaOH solution. It has been found that the alkaline medium, and especially caustic soda solution, may further advantageously already contain calcium ions, for example 10 to 50% of a 0.1 to 0.3N CaCl 2 solution.
- a significant advantage is that a high order of small apatite needles is obtained, which structurally have a great similarity to native enamel. With appropriate substrate orientation, there is virtually no difference between grown apatite and original tooth material.
- dentin layers or dentin-like layers on tooth material can be achieved.
- the grown up layer corresponds in crystallite size and crystallite order to natural dentin.
- the softening temperature of the gel is slightly above the normal body temperature (38 to 42 0 C), a melting of the gel is prevented during the exposure time. Thus, an uncontrolled mineralization can be avoided.
- apatite is grown on tooth material by
- a first gel comprising gelatin and phosphate ions is applied to the alkaline medium pretreated tooth material.
- one of the steps (iiia) or (iiib) or both steps is carried out, ie the application of a second gel which is free of phosphate ions, with this second gel the first gel layer being covered and / or the application of a medium containing calcium ions ,
- this gel can be applied directly (ie without treatment with the gel (iiia)) on the first gel.
- a first gel which also contains at least one calcium phosphate compound
- Suitable calcium phosphate compounds include fluoroapatite, monetite, brushite, amorphous calcium phosphate, hydroxyapatite, etc.
- the calcium phosphate compound is preferably used in the form of particles, and most preferably in the form of spherical or predominantly spherical particles.
- the size of the particles is preferably 5 to 50 .mu.m, in particular 10 to 20 microns.
- 5 to 30% by weight of calcium phosphate compounds are added to the first gel.
- the first gel comprises 5 to 30 Wt .-% predominantly spherical fluoroapatite particles with a size of 5 to 50 microns.
- the double-diffusion method has neither opened up the possibility of remineralizing enamel on humans, nor of implying this possibility in any way.
- the experimental setup used in the double diffusion method causes the formation of small beads and does not allow the growth of uniform layers of apatite material on a substrate. This is only possible by the procedure according to the invention.
- the invention can be used in particular in humans.
- smaller carious defects can be healed by induced remineralization or sensitive areas on the tooth can be covered with a protective apatite layer.
- the procedure for treatment is preferably as follows: The carious site is first treated with an alkaline medium, for example with sodium hydroxide solution, and then with a thin layer of about 50 0 C warm phosphate-containing gel coated or applied with a suitable syringe that can be warmed. The gel immediately solidifies on the tooth surface and is covered by the same method with the guard gel or a calcium ion-containing agent. If necessary, a mouthwash of approximately 10 minutes is then carried out 1 to 3 times a day with a calcium solution.
- a gel containing calcium ions for example, a 0.1 to 0.5 N calcium gel is preferred, by means of which the application is further simplified.
- a matching cap which may be made of plastic or metal, so that the patient is not disabled and the remineralization can take place undisturbed.
- the entire row of teeth can also be protected with a splint, such as that used for teeth grinding. Every two days, the gel is changed, on this occasion, the affected tooth is cleaned and disinfected.
- a first gel is applied to the tooth material.
- This gel contains gelatin as well as phosphate ions and optionally further components, in particular calcium phosphates, as explained above.
- the content of gelatin in the first gel is preferably from at least 15% by weight, more preferably from 25% by weight to 40% by weight, more preferably up to 30% by weight.
- gelatin has a function of forming the morphology of the apatite formed. It has surprisingly been found that with the use of gelatin an apatite material is deposited on the surface of tooth material, which has a great similarity to native enamel or dentin. On the other hand, when other organic matrices were used, other apatite crystal morphologies were observed, so that apatite is not formed on the surface of the tooth material as intended by the present invention.
- Gelatin is a polypeptide which can be obtained, in particular, by hydrolysis of the collagen contained in the skin and bones of animals. Gelatin usually has a molecular weight of 15,000 to over 250,000 g / mol and can be recovered from collagen under acidic or alkaline conditions. According to the invention, the following gelatins are preferably used: acid hydrolyzed types of gelatin (type A), eg made from pork rind or calf skin with a high bloom value, eg 250 to 350 bloom (the Bloom value means a parameter which characterizes the gel strength; in general, the higher the Bloom value, the higher the proportion of long-chain molecules in the gelatin and the higher the gel strength).
- type A acid hydrolyzed types of gelatin
- the Bloom value means a parameter which characterizes the gel strength; in general, the higher the Bloom value, the higher the proportion of long-chain molecules in the gelatin and the higher the gel strength).
- the first gel further comprises phosphate ions.
- phosphate ions are a basic constituent of the apatite composed of calcium phosphate.
- the concentration of phosphate ions in the first gel is preferably at least 0.01 mol / l, more preferably at least 0.05 mol / l and up to 0.5 mol / l, more preferably up to 0.2 mol / l and especially 0.08 mol / l.
- the first gel preferably has a softening temperature that is above normal body temperature so that the gel is solid at body temperature.
- the softening temperature of the first gel is preferably in the range from 38 to 45 0 C, more preferably of 38 to 42 ° C.
- the first gel is preferably applied in heated form, for example heated to 45 to 55 ° C. After application, the gel cools down and solidifies.
- a second gel a so-called protective gel
- the first gel layer is covered with this second gel.
- the protective gel which functions as a gel top layer, surprisingly causes the mineralization, ie the formation of apatite, to take place predominantly or exclusively at the tooth surface and not at the boundary layer of gel liquid.
- the two-layered gel structure achieved in the process according to the invention results in the formation of apatite on the tooth material and not in crystallization or formation of apatite spheres within the gel, as described in the prior art. Due to the two-layer structure thus a practicable and technically meaningful remineralization of the teeth is possible.
- the pH and the gel concentrations of the second gel correspond typically those set forth herein for the first gel.
- the second gel preferably has a softening temperature of 38 to 45 0 C 1, in particular from 38 to 42 0 C and is preferably applied to 45 to 55 0 C heated.
- a calcium ion-containing medium is finally applied.
- the calcium ion-containing medium provides the further basic building material needed to form apatite, calcium ions. These calcium ions diffuse through the protective gel and the first gel layer to the surface of the tooth material and are deposited there as apatite.
- the concentration of calcium ions in the calcium ion-containing medium is preferably at least 0.01 mol / l, more preferably at least 0.05 mol / l and up to 0.5 mol / l, more preferably up to 0.2 mol / l, and especially 0 , 13 mol / l.
- a uniform layer of parallel or radiantly grown apatite crystallites can be formed. Furthermore, this layer shows no or only a submicrometer edge gap to the native tooth material.
- the growth direction of the apatite crystallites takes place independently of the orientation of the enamel prisms perpendicular to the substrate, so that with appropriate orientation of the enamel prisms, the longitudinal orientation of the artificially grown crystals is largely identical to the crystals in the prisms.
- the order of molten crystals and grown fluoroapatite is the same. Within the layers, a dense and uniform packing can be observed.
- the applied apatite layer has a Vickers hardness equal to that of the native enamel.
- the apatite layers applied according to the invention have, in particular, a Vickers hardness in the range from 250 to 400 HV.
- the first gel used is a gelatin-glycerol gel.
- the weight ratio of gelatin to glycerol is preferably 1: 5 to 5: 1, in particular 1: 2 to 2: 1.
- Glycerol has the effect of raising the softening point of the gel above normal human body temperature. The gel strength achieved is necessary to maintain the two-layer system during mineralization, allowing targeted, controlled crystal deposition. In a liquid gel it would come to a spontaneous precipitation of finely crystalline material, which does not grow on the tooth.
- the first gel preferably further contains fluoride ions.
- the fluoride may be added, for example, as sodium fluoride or ammonium fluoride.
- fluorine rich apatite or fluoroapatite may be grown on the surface of the tooth material.
- fluoroapatite is more acid-resistant than the carbonate-containing hydroxyapatite of natural enamel, yet the morphology of the fluoroapatite-forming layers is very similar to that of native enamel.
- the rate of growth of the apatite or fluoroapatite is determined inter alia by the pH of the first gel.
- the first gel has a pH of from 2.0 to 6.0, especially from 4.0 to 6.0, more preferably from 5.0 to 5.5.
- a protective gel or a calcium ion-containing gel is used as a second gel.
- This gel covers the phosphate ion-containing first gel layer.
- the second gel preferably contains no materials which are to be incorporated into the apatite, that is, in particular phosphate ion, calcium ion and / or fluorine ion-free, it is in certain Embodiments make it possible to apply a gel containing calcium ions as a second gel. Even with this growth rates of several microns per day were achieved.
- Gelatin can also be used to form the second gel, with a gelatin-glycerol gel being preferred.
- another gel for example selected from polysaccharides, such as agarose or carragnan, and carboxymethyl cellulose can be used.
- the tooth material coated with the first gel and optionally with protective gel can be treated with a calcium-containing medium.
- a calcium-containing medium for example, a calcium ion-containing solution and / or a calcium ion-containing gel can be used.
- the calcium ion-containing medium is preferably prepared using a water-soluble salt containing calcium ions, for example from CaCl 2 .
- the calcium ion-containing medium preferably has a pH of 6 to 8.
- the two constituents of apatite namely phosphate ions and calcium ions, are each supplied separately as a separate component, the calcium phosphate formation taking place on the tooth material surface.
- the phosphate gel is preferably mixed with a buffer system, preferably an acetic acid buffer or ⁇ - ⁇ - ⁇ -tris (hydroxymethyl) methylamine buffer.
- the tooth material Before the treatment with the alkaline medium or / and with the first gel, the tooth material can be pretreated, in particular degreased, etched or / and rinsed.
- the tooth surface may first be degreased with ethanol and etched with phosphoric acid and then rinsed with deionized water.
- the inventive method is particularly suitable for treatment of human teeth or enamel.
- carious defects can be treated by remineralization or even the tooth material can be prophylactically covered with a protective apatite or Fluorapatit Anlagen.
- the apatite layers form on both enamel and dentin as a substrate.
- the invention further relates to a composition or kit which is particularly suitable for the use described above and a) an alkaline medium b) a first gel comprising gelatin and phosphate ions, and d) a second gel which releases of phosphate ions or / and c2) comprises a calcium ion-containing medium.
- a human tooth (arbitrary) was separated from its root and sawed the crown in about 0.5 mm wide slices.
- the disks were immersed in a 30% phosphoric acid solution for 30 seconds, washed with deionized water and dried.
- Another gel was prepared from 8.56 g of gelatin, 8.24 g of 85% glycerol solution and 11.76 g of H 2 O.
- a 0.133 molar calcium solution was made
- the surface of the toothed discs was coated with about 0.5 ml of the phoshat inconveniencen gel. After solidification, it was covered with about 0.5 ml of the additive-free gel.
- the toothed disc was inserted into a plastic tube sealed on one side and stored in a calcium solution at 37 ° C. The gel and solution were renewed every 7 days, 16 times in total.
- the sample was broken up perpendicular to the cut surface in order to be able to measure the layer thickness. It formed a uniform layer of elongated crystallites with a layer thickness of 7.2 microns. This corresponds to a growth rate of about 450 nm / week.
- Example 2 The procedure is analogous to Example 1, but first a treatment with an alkaline solution was carried out. Furthermore, storage was carried out in calcium solution as described above or in SBF (Simulated Body Fluid with 142 mM Na + , 5 mM K + , 15 mM Mg 2+ , 25 mM Ca 2+ , 148.8 mM Ch, 4.2 mM HCO 3 2 -, 1 mM HPO 4 2 -, 0.5 mM SO 4 2 ) or dry.
- SBF Simulated Body Fluid with 142 mM Na + , 5 mM K + , 15 mM Mg 2+ , 25 mM Ca 2+ , 148.8 mM Ch, 4.2 mM HCO 3 2 -, 1 mM HPO 4 2 -, 0.5 mM SO 4 2
- Example 2 The procedure corresponds to Example 2, wherein instead of the calcium solution, a calcium gel was used. Here, too, comparable growth rates were noted.
- Example 4 The procedure corresponds to Example 4, wherein the protective gel was omitted. Again, growth rates of 1, 8 to 5 microns / day were obtained.
